The three sizes are three measurements: the size the agency reported when the fire was out, the burned area MTBS drew from satellite imagery before and after, and the GIS area inside the final perimeter, unburned islands included. They rarely agree exactly.

Every fire of 2009 Alaska fire history

Sources

Perimeters from the National Interagency Fire Center’s Interagency Fire Perimeter History, compiled from the Forest Service, BLM, BIA, Fish and Wildlife Service, National Park Service, the Alaska Interagency Fire Center and CAL FIRE. Burned areas and ignition dates from Monitoring Trends in Burn Severity (MTBS), a program of the US Geological Survey and the USDA Forest Service. Fire reports from Short, Karen C. 2022, Spatial wildfire occurrence data for the United States, 1992-2020 [FPA_FOD_20221014], 6th Edition, Forest Service Research Data Archive, doi.org/10.2737/RDS-2013-0009.6. Records before 2014 were joined by this site: a fire report to the burned area its MTBS identifier names, a perimeter to the burned area it lies in when the names or the sizes agree. Incident figures from ICS-209-PLUS: St. Denis, Lise A., Karen C. Short, Kathryn McConnell, Maxwell C. Cook, Nathan P. Mietkiewicz, Mollie Buckland and Jennifer K. Balch, 2023, All-hazards dataset mined from the US National Incident Management System 1999-2020, Scientific Data 10, 112, doi.org/10.1038/s41597-023-01955-0; data on figshare, doi.org/10.6084/m9.figshare.19858927.v3, licensed CC BY 4.0. This site matched each incident to the fire by the dataset’s own links where it has them, and otherwise by name, start date, state and size, and left out figures too large to be possible for a fire of its size.
